I Toall whom t may concern:

Be itknoyvn that we, HiLLiAnD CBAT- .TLEs .and LUTHER F. BATTLEs, citizens of -the United States, residing at Hambden, in

l.thel county of Geauga and State of Ohio,

have invented a new and useful 'Tying Apparatus, of which the following is a specification.

Thisy invention reliatesto a device for tyinga cord -in a knot after the cord has been passed around a bundle. i It relates generally to machinery in which thetying of knots is required, and particuyIarly to harvesting machinery.

A An, object ot this invention is to produce an efficient-device. which may be applied to and usedin connection with machinery in which thetying of bundles constitutes a part of the work to be performed.

Another object of thisinvention is to produce a device capable of operation in any lposition vwithout impairing its eilicieiicy'.

A' further object of this 'invention is to produce a device for use .on harvesting machinery, such as grain binders and grain shockers, where a durable, efiicient and comafter more; fully set forth and claimed.

- i drawings forming part of this specification,- wherein like characters denote correspond- `ing 'parts 1n the several views, and 1n In describing the invention in detail, reference will be had to the accompanying which- Figure l illustrates an Aelevation partly in section of the invention, showing also the gear wheels of a harvesting machine einployed in operating it; Fig. 2 illustrates a top plan view of theinvention; Fig.. 3 illustrates a 'fragmentary View of'the gearing that may be employed-in operating the invention; Fig. 4 illustrates a top plan view of the knetter.; Fig. 5 illustrates an underneath plan view of the knotter; Fig. 6 illustrates an enlarged detail view ofthe cord disk and also of .the cord disk clamp; Fig, 7

- to 18 are detail views illustrating the successive positions of'v the knotting bill and cord while the knot is being tied; and Fig. 19 illustrates an enlarged detail view of the knot tied by the invention.

Thebundle tying devices, as such, at present employed in harvesting machinery are practically non-adjustable. ln the absence 'of auxiliary attachments they bind all bundles at approximately the same distance from their butt ends. without regard to the length of the grain stalks. lVhether of wheat, oats, rye. barley or other grains, the bundles v are tied at the-same distance from their butt ends. lVliere the same tying device must be used in harvesting the different kindsof grains, it is obvious that the device should be capable of ready adjustment in order vthat the bundles may be bound in proper position in respect to .their length. Being manually adjustable, in a inoments time, with relation to the length of the bundle to be bound, our invention provides a device capable of tying bundles and shocks of grain of any kind at that distance hetween their en ds best adapted to securel To accomplish this vo-ur 'inventioir them. has been constructed so that its chief elements, that is to say, the. knotter part and the needle part, are capable of being operatively attac-hed on a member or members.

readily movable. toward or away from the butts of the bundles in the direction of the length of thesam'e. Moreover the construction of the knetter and needle is such that they will operate in a vertical position, in a' horizontal position, or at any angle. ln view of this advantage it'is obvious that the device may lie employed on any machine requiring bundle binding; for the adjustable member or members supporting the needle and knotter may. be. placed in any position necessary to parallel the-length of the bundles during the moments of'binding. i In the drawin he gearing showntor transmitting motion tothe shafts support-'- mechanism of our limproved shocking mathrough the square channel lcentrally provided through the entire length of the knotehine'whic'h forms the subject-matter of a separate application. Said gears for imparting motion are shown here only for the purpose of facilitating comprehension of this invention.

In the drawings, referring especially to Fig. 3, 5 indicates the main drive shaft to theend of which issecured a bevel gear 5. The shaft 14c has a beveled gear 14 loosely 'running thereon and this gear is adapted to mesh with and therefore be driven by the bevel gear `5a. Slidably keyed to the shaft 14c is a friction clutch 14b which is-adapted to govern the actuation of the shaft 14c wheny thrown into and out of engagement with the rea-rfface of gear 14. The actuation of this clutch may be accomplished in any well known manner.

As shown inf-Fig. 1, bevel gear 14e is keyed to Asquare shaft l-whieh extends upwardly ter shaft 15g. The upper end of said shaft 15g is`journaled in the cross plate 21 (Fig. 1.) Bevel gear 14e has a wrist pin 14 Cog wheel 14" has: a wrist pin 14h. These wrist pins are connected by pitman 14g. 14 drives 14j, whiehfis keyed (Fig. 1) to the square shaft 16. `Said shaft y16 slidingly penetrates the channel centrally provided through the length of shaft 16, which is journaled at the top in cross plate 21. Said shaft 16c carries cog wheel 16", which engages the cogs provided on the knotting needle 17. By this means needle 17 is projected when a bundle is to be tied, and withdrawn when the tying is completed, it'being obvious that cog wheel 16b must be of suflicient diameter to project needle 17 lthe required distance. Needle 17 is supported on and guided in the direction of its movement by a. guide'la, which also serves to hold the needle in engagement with 16". l'The guide 17 is heldv by hangersas 17h, secured to cross plate 21. A cross bar 17cv braces the lower ends of said hangers-and also serves.

as al bearing for lshaft 16. Said bar 17c lfurther contains an eye for the reception of a guide rod as 17d., the opposite ends of -which are secured. to some suitable part of the main machine frame. -A quadrant 20a is. vertically secured to a. support as 20, which may be fastened to any Suitable part of the framework of the main machine em- -4 ploying this device. Operating lever 20d is attached at i-ts lower end to a horizontal shaft 20, which may be journaled in stationary parts of the machine employing this invention. To shaft 20l are ixedly secured the' forwardly andu-pwardly extending arms 20a, the said arms being of suflcient length to meet imaginary extensions of the bill hook 22e.

shafts 15b' and 16. The front ends of arms 2 0 are connected to the horizontal plate 21 by the conneetingpieces 2Ob and 20, the connections ateach end of 20b being pivotal. rfhe upper ends of the shafts 15g and 16c projecting beyond the plate 21 are provided with collars thereby rotatably securing said shafts to the crossv plate 21.- Shaft 15H driven by square shaft 15 rotates in the direction of the arrowsas shown'in Fig. 1. Thus the needle and the knetter operatively supported on a common frame may be raised or lowered at will so as to bind -bundles-or shocks around their centers or is provided with a cam 22W, which contacts with bell crank lever 22 (Fig. 5) when the shaft rotates. 22l is fulerumed to frame 22 by pin 22. and operates lever 22, secured tothe frame by clasps 22p. A circular linger 22" pivotally connects 22m with the linger 22e, which has a hooked end for the purpose of supporting and guiding the binding cord. )Vhen 22W contacts with 221, 22e is swung rearwardly and downwardly so as to draw the binding cord (held between-needle 17 and cord disk wheel ll) into the path 'of the l The large face of cam 22w acting'on 22 holds 22e down long enough to permit 22d to swing over the cord (Fig. 13). lVhen 22Vreleases 22, said 22l and connected parts are returned to normal position by spring 222. Following the disengagement of cam 22v with 221, the cogs of segmental wheel 15d on shaft 15e mesh with bill hook wheel 15, lwhich operates bill hooks 22d and 22. As shown in Fig. 9, bill hook 221 is pivotally secured at the lower end of the heel of 22'J and between the fingers thereof. As the bill hooks rotate, the roller provided on bill hook 22d engages a shoulderfin the guide channel of CJI the cord secured by clamp 15h. `When the mechanism is actuated, needle 17 is project# ed in proper position over the bill hooks and cord disk wheel (Fig. 12), the two strands of cord being supported by 22e. As soonas 'the cord is held the knot is tied in the 'manner illustrated by Figs. 12 to 18.

Cord disk wheel' 15l is operated in the following manner A trip pin 15m carried by shaft 15g is arranged to contact at the proper time with crank 223'. Shaft 22s secured by clasps 22" connects crank 223 with the long crank Through the pivotally held connecting arm 22k, the movement of 224 is imparted toa vertically disposed shaped lever 15j (Figs.` 5 and G), said lever being vieldingly mounted on a horizontal shaft journaled in frame 22. At its rear end 15l carries a dog 15, yieldingly secured by a spring, The office of this dog is to engage one o'f the .six notches provided on the hub of the cord disk wheel 15, whereby to turn said 15 one-sixth of its circumference during Ithe' process of 'tying once. To keep the cord taut, a tension clamp 15 is pro vided for the forward part ofvl, 15" being vieldingly mountedadjacent its lower end to a shaftA fixedly s cured to the frame. Said clampis held in'engagement with cord disk wheel 15i Aby spring 15P. Then the cord disk wheel 15i is turned one notch, spring 22 acting on lever 222 serves to reposition 15j so that dog 15k engages the next succeeding notch for the next'operation.

A knot having been tied on the bill hooks, the next steps are the threading of said cord disk wheel, the cutting of the cords betweenthe bill hooks and cord disk wheel, and the removal ofthe knot from the bill hooks, all

ofwhich-are accomplished in the following manner: Shaft 15g carries a short pm 22k whichcontac'ts with bell crank lever 221, fu-

crumed to knotter frame at 220. Through toggle lever 22g, crank and shaft 22 arel operated, To shaft 22t are liXedly secured thevoval-shaped knife 22i and the knot discharger 22". A moment before the bill hook ucompletes its revolution and comes to rest i A spring 22v serves ciated parts to their normal pgsition after Y with the tied knot, .the cord disk wheel 15l advances, and'while so advancing, the notches in they spokes catch the cord and bind it with the aid of clamp 15h as above shown. Immediately shaft 22, 4thr ou,f, ;h the action of 22kon22f, raises knife 22 and also knot discharger'22h so that the cord is cut and the knot dischargedimultaneously.

to return 22j and Vassodlsengagementwith; 22k.

- Asillustrated in 2, theknotter part" of the device and the `needle part of the desaid clalnp l the plate,

vice are so disposed that'the binding cord' is held directly across the. pathway of the thing to be-bound. By, the proper manipulation` of the quadrant, the knotter and needle parts are elevated or lowered as a unitary device, and the cord is held at 'that height at which it is desired tpl; bind they bundle. j
